Lucy, although I'm no handwriting expert, Image 2 on the line for Geoffroi Goepp reads 27 7bre or 27 September in English. You can assume 1833 from the line above.  This can be confirmed when you go to Heiligenstein, N, 1833, i 5, #14 for Geoffroi which shows the month as Septembre. The ___ember months are often shown in Alsace (and many other places) with a number before them. I believe this is from the Latin Sept = 7 so 7bre Oct = 8  so 8bre Non = 9 so 9bre Dec = 10 or 10bre which is usually shown as Xbre. My french is limited but most of the rest of the months are very close to English except Aout which is August. There is an "Idem" date listed which just means ditto or "" in English. It means the as the record before it. When just idem is listed, like for Sophie Goepp,  it means the same date (often twins, but check the actual records). You can also see on that next page where idem is listed for the month.  Hope this helps, Dave
